In a large bowl combine egg yolks, pumpkin, brown sugar, brandy and spices. Stir in milk. Fold in bread cubes, pecans and dates. In a smaller mixer bowl beat egg whites until stiff peaks form (tips stand straight). Fold egg whites into bread mixture. Turn into a 10 x 6 x 2 inch baking dish. Bake at 325 degrees for 45-50 minutes or until a knife inserted near center comes out clean. Serve warm with light cream.
